Figure 4. Sensitivity to apoptosis under CD3 and CD3/CD28 stimulation.

Figure 4

A. Representative plots of CD25 upregulation under CD3 stimulation in splenocytes from NOD and wild type mice. Quantitative conversion to express CD25 in splenocyte cultures from NOD (n = 4) and wild type females (n = 6) under CD3 and CD3/CD28 stimulation as compared to unstimulated cultures (naïve). Other delineates all CD4 cells. B. Proliferation rates of CD4+ T cells that upregulated CD25 expression (CD25→CD25+) as determined from CFSE dilution in mixed cultures of splenocytes from NOD (n-4) and wild type mice (n = 5) under CD3 and CD3/CD28 stimulation. C. FasL-induced apoptosis in reference to CD25 expression in gated CD4+ T cells within mixed splenocyte cultures from NOD and wild type mice (n = 4) under CD3/CD28 stimulation. Apoptosis was also measured under inhibition of proliferation with Mitomycin C (n = 3).
